NOTE: The port LEDs and system LEDs on the front panel are not the same for all
models. Figure 1-7 shows the LEDs on the PowerConnect 7024, PowerConnect
7024F, and PowerConnect 7048 switches.
Switch Ports
The PowerConnect 7024 and PowerConnect 7024P front panel provides
24 Gigabit Ethernet (10/100/1000BASE-T) RJ-45 ports with four SFP combo
ports that have an auto-sensing mode for speed, flow control, and duplex
mode. SFP transceivers are sold separately. The PowerConnect 7024P switch
ports are IEEE 802.3at-2009-compliant (PoE Plus) and can provided up to
30W of power per port.
The PowerConnect 7024F front panel provides 20 Gigabit Ethernet
(10/100/1000BASE-FX) SFP ports plus 4 combo ports for copper or SFP
media support.
The PowerConnect 7048, PowerConnect 7048P, and PowerConnect 7048R
front panel provides 48 Gigabit Ethernet (10/100/1000BASE-T) RJ-45 ports
with four SFP combo ports. The PowerConnect 7048P switch ports are
IEEE 802.3at-2009-compliant (PoE Plus) and can provided up to 30W of
power per port.
The front-panel switch ports have the following characteristics:
• The switch automatically detects the difference between crossed and
straight-through cables on RJ-45 ports.
• SFP ports support both SX and LX modules.
• RJ-45 ports support half- and full-duplex mode 10/100/1000 Mbps.
Console Port
The console port is for management through a serial interface. This port
provides a direct connection to the switch and allows you to access the CLI
from a console terminal connected to the port through the provided serial
cable (RJ-45 to female DB-9 connectors).
The console port supports asynchronous data of eight data bits, one stop bit, no
parity bit, and no flow control. The default baud rate is 9600 bps.

10 Getting Started Guide
Out-of-Band Management Port
The Out-of-Band (OOB) management port is a 10/100/1000BASE-T
Ethernet port dedicated to remote switch management. Traffic on this port is
segregated from operational network traffic on the switch ports and cannot be
switched or routed to the operational network.
USB Port
The Type-A, female USB port supports a USB 2.0-compliant flash memory
drive. The PowerConnect switch can read or write to a flash drive formatted
as FAT-32. You can use a USB flash drive to copy switch configuration files
and images between the USB flash drive and the switch. You can also use the
USB flash drive to move and copy configuration files and images from one
switch to other switches in the network.
The USB port does not support any other type of USB device.
Reset Button
The reset button is accessed through the pinhole and allows you to perform a
hard reset on the switch. To use the reset button, insert an unbent paper clip
or similar tool into the pinhole. When the switch completes the boot process
after the reset, it resumes operation with the most recently saved
configuration. Any changes made to the running configuration that were not
saved to the startup configuration prior to the reset are lost.
Port and System LEDs
The front panel contains light emitting diodes (LEDs) that indicate the
status of port links, power supplies, fans, stacking, and the overall system.
Additionally, the PowerConnect 7024P and PowerConnect 7048P switches
contain LEDs that provide information about Power over Ethernet Plus
(PoE+) status and activity on the ports.
For information about the status that the LEDs indicate, see the User’s
Configuration Guide.

Getting Started Guide 11
Stack Master LED and Stack Number Display
When a switch within a stack is the master unit, the stack master LED, which
is labeled M, is solid green. If the M LED is off, the stack member is not the
master unit. The Stack No. panel displays the unit number for the stack
member. If a switch is not part of a stack, the M LED is illuminated and the
stack unit number is 1.

PoE and full redundancy for the switch.
PC7048R and PC7048R-RA
PowerConnect 7048R and PowerConnect 7048R-RA switches are designed as
top-of-rack switches and include two internal, replaceable, AC power supplies
for redundant or load-sharing operation. Each power supply can provide
300 watts and includes hot-swap support. This means you do not need to
power-down the switch to remove or replace one power supply while the other
power supply is operating normally. However, it is necessary to remove power
from the power supply that is being removed or replaced.
CAUTION: Remove the power cable from the modules prior to removing the
module itself. Power must not be connected prior to insertion in the chassis.
Ventilation System
Three fans cool the PowerConnect 7024, PowerConnect 7024F, and
PowerConnect 7048. The PowerConnect 7024P and PowerConnect 7048P
each have two fans, with a third fan in the internal power supply.
The PowerConnect 7048R has two hot-swappable fan trays with one fan each.
Locator LED
The back panel includes an LED to help identify the switch within a rack or
room full of switches. From your remote management system, you can set the
LED to blink to help you or a local technician identify the physical location of
the switch.

14 Getting Started Guide
Installation
Site Preparation
PowerConnect 7000 Series switches can be mounted in a standard 48.26-cm
(19-inch) rack or left freestanding (placed on a flat surface) and function as
stand-alone switches.
Before installing the switch or switches, make sure that the chosen
installation location meets the following site requirements:
• Power — The switch is installed near an easily accessible 100–240 VAC,
50–60 Hz outlet.
•
Clearance — There is adequate front and rear clearance for operator
access. Allow clearance for cabling, power connections, and ventilation.
•
Cabling — The cabling is routed to avoid sources of electrical noise such
as radio transmitters, broadcast amplifiers, power lines, and fluorescent
lighting fixtures.
•
Ambient Temperature — The ambient switch operating temperature
range is 0 to 45ºC (32 to 113ºF) at a relative humidity of up to 95 percent,
non-condensing.

container.
2 Open the container or remove the container top.
3 Carefully remove the switch from the container and place it on a secure
and clean surface.
4 Remove all packing material.
5 Inspect the product and accessories for damage.
Mounting the Switch
WARNING: Read the safety information in the Safety and Regulatory Information
as well as the safety information for other switches that connect to or support the
switch.
The AC power connector is on the back panel of the switch.
Installing in a Rack
WARNING: Do not use rack mounting kits to suspend the switch from under a
table or desk, or attach it to a wall.
CAUTION: Disconnect all cables from the switch before continuing. Remove all
self-adhesive pads from the underside of the switch, if they have been attached.
CAUTION: When mounting multiple switches into a rack, mount the switches
from the bottom up.
1 Place the supplied rack-mounting bracket on one side of the switch,
ensuring that the mounting holes on the switch line up to the mounting
holes in the rack-mounting bracket. Figure 1-11 illustrates where to mount
the brackets.

16 Getting Started Guide
Figure 1-11. Attaching the Brackets
2 Insert the supplied bolts into the rack-mounting holes and tighten with a
screwdriver.
3 Repeat the process for the rack-mounting bracket on the other side of the
switch.
4 Insert the switch into the 48.26 cm (19 inch) rack, ensuring that the rack-
mounting holes on the switch line up to the mounting holes in the rack.
5 Secure the switch to the rack with either the rack bolts or cage nuts and
cage-nut bolts with washers (depending on the kind of rack you have).
Fasten the bolts on bottom before fastening the bolts on top.
CAUTION: Make sure that the supplied rack bolts fit the pre-threaded holes in the
rack.
NOTE: Make sure that the ventilation holes are not obstructed.

Getting Started Guide 17
Installing as a Free-standing Switch
NOTE: We strongly recommend mounting the switch in a rack.
Install the switch on a flat surface if you are not installing it in a rack.
The surface must be able to support the weight of the switch and the switch
cables. The switch is supplied with four self-adhesive rubber pads.
1
Attach the self-adhesive rubber pads on each location marked on the
bottom of the switch.
2 Set the switch on a flat surface, and make sure that it has proper
ventilation by leaving 5 cm (2 inches) on each side and 13 cm (5 inches) at
the back.
Stacking Multiple Switches
You can stack PowerConnect PowerConnect 7000 Series switches up to
12 switches high, supporting up to 576 front panel ports. When multiple
switches are connected together through the stack ports, they operate as a
single unit with a larger port count. The stack operates and is managed as a
single entity.
NOTE: If you are installing a stack of switches, you need to assemble and cable the
stack before powering up and configuring it. When a stack is powered up for the
first time, the switches elect a Master Switch, which may occupy any location in
the stack. The Master LED on the front panel is illuminated on the master unit.
Creating a Switch Stack
Create a stack by connecting adjacent units using the stacking ports on the
back panel of the switch. Stacking modules are sold separately. Figure 1-12
shows the switches connected in a ring topology, which is the recommended
topology for a stack.
1
Install a separately purchased stacking module in one of the rear expansion
slots for each of the switches in the stack.
2 Connect one of the short stacking cables into either of the stacking ports
of the top switch and the switch directly below it.
If necessary, use a separately purchased, long (3 meter) stacking cable to
connect the switches.

18 Getting Started Guide
3 Repeat this process until all of the devices are connected.
4 Use the remaining stacking cable to connect the remaining free ports,
one each on the top and bottom switches.
Figure 1-12. Connecting a Stack of Switches
The stack in Figure 1-12 is connected in a ring topology and has the following
physical connections between the switches:
• The XG1 port on Unit 1 is connected to the XG2 port on Unit 2.
• The XG1 port on Unit 2 is connected to the XG4 port on Unit 3.
• The XG3 port on Unit 3 is connected to the XG2 port on Unit 1.
Stacking Standby
The stacking feature supports a Standby or backup unit that assumes the
Master unit role if the Master unit in the stack fails. As soon as a Master
failure is detected in the stack, the Standby unit initializes the control plane
and enables all other stack units with the current configuration. The Standby
unit maintains a synchronized copy of the running configuration for the
stack. During switchover, all the ports are brought down and brought up to
avoid possible loops and to get new master software applications to a
consistent state.
The Standby unit is pre-configured in the stack; however, you can use the CLI
to select a different stack member as Standby. See the User’s Configuration
Guide or the CLI Reference Guide for more information.
